C-mount

The lens mount is an interface that allows a lens to be attached to an interchangeable lens camera. As of 2018, Canon has produced 8 mainstream lens mounts.However, a lens mount does not exist simply as a means of attaching a lens to the camera. It also facilitates communication between the camera and the lens, enabling both to perform a wide range of functions.Canon’s first mount was a standard-thread-type screw mount that supported the mechanisms found in rangefinder cameras. Subsequent mounts evolved with the times in order to meet users’ expectations, delivering such advancements as automatic aperture, auto-exposure and autofocus mechanisms.The newest mount, the RF mount, promises even better image quality and usability thanks to its large mount diameter, short back focus distance and enhanced lens-camera communication system. It is indeed a mount designed for the future.It can be said that the lens mount is the key to the future evolution of both lenses and cameras.
